Very wrong
NDSMELODY:


p = [RE/R+b]^2

take square root of both sides

₹p = ₹[RE/R+b]^2

₹p = RE/R+b

cross multiply
₹p(R+b) = RE

open bracket and simplify

₹p*R + ₹p*b = RE

COLLECT LIKE TERMS

₹p*b = RE - ₹p*R

₹p*b = R(E-₹p)

.divide both sides by E-₹p

R = ₹p*b/E-₹p........



Note that ₹ stands for square root and * for multiplication sign.....good luck.

x is 36°

Fact:
<A = < D = x ((base angles of isosceles triangle)
Also, <A = < D = <BCD = x

Let <ABC be y, therefore <BCD is also y (base angles of isosceles triangle)

From ∆ABC; y + y + x = 180°,
2y + x = 180° ............Eqn 1

From ∆BCD; x + x + (180° - y) = 180°,
y = 2x ......... Eqn 2

Put Eqn 2 in Eqn 1:
2(2x) + x = 180°,
5x = 180°,
x = 36°

The answer given here is an assumed or guess solution with no basis. That is the reason why I brought it here to cross fertilize idea with those not on that page before I say my own view here.
But I have a reservation that nobody is a paragon on knowledge!

mrphysics:
.

Whenever you take flight from a particular place to another, you have absorbed more ionizing radiations that someone living 20km from a nuclear power plant. When you take 1-9 cigarettes a day, you take same risk as someone who took a dose of 3.4Sv from a bomb blast.


The words of MrPhysics grin grin grin
You did very well. In fact, I've been planning to make a write up like this here but I don't have to bother myself again. Thank you.

But I have problem with the quited part of your write up above most especially linking cigeratte smoking to an exposure of 3.4Sv.. I don't think that is through..
Even for radiation workers, the occupational dose limit is 50mSv per annum (0.05 Sv) and not exceeding 20mSv (0.02 Sv) over a 5 years average..

So it is not possible for smokers to be exposed to 3.4 Sv for smoking just a few sticks of cigarette..
In fact, 3Sv of radiation exposure can kill (lethality). Threshold values for cataract, sterility, epilation etc are far less than 3.4 Sv..

cheango:
*Below are submissions of three professors of radiation physics in UI copied from Science Faculty platform to debunk the narratives in the trending audio on 5G*

*Dr Popoola*

The man who made this audio message can be likened to someone who is interpreting a strange language he has never studied. He does not know what he's saying.
In a simple language, the so called 5G (fifth generation) is a transmission at far higher frequency range than 4G. This feature implies transmission of greater quantum of energy (signal) per time, hence heavy data (such as images) will download faster and will be transmitted at higher resolution. Meanwhile this may require more booster antennas at closer ranges in order to travel very far because high frequency signals get attenuated faster than low frequency signals. In short 5G will be able to accommodate larger data than 4G.
Generally, people have always displayed some fear each time a new technology arose. The fear attributed to mobile technology is that the signals (waves) are injurious to humans. Meanwhile all mobile signals most fall within microwaves (extreme end of radio waves) which are non ionizing radiations. Ionizing radiations like x-rays and gamma rays have far higher frequencies and exposure to human body may be injurious. However are not used for mobile telecommunication.
The man's use of the word 'radioactive' reveals that he is completely ignorant of what he claims to be explaining. The word Radioactive is from Radioactivity which is a completely different phenomenon from radio wave. Technology is more than speculation. It is a product of basic scientific theories.

*Prof Farai:*

������I remain proud of you Tunde. Just look at the confidence with which he was talking nonsense. I was just wondering how I would present a rejoinder in a language that we will all understand and without sounding know it all. You have captured all with the appropriate words. It is now up to anybody to allow him/herself to be misled. God bless you richly, my brother.

*Prof Jibri:*
I really don't understand over stretching of a simple scientific matter. Simple basic physics which our Prof. Farai has laid to rest for us as a guru in Radiation business. Use E = hf from modern Physics and the frequencies or the wavelengths of the regions for the G's what amount of energy do you arrive at. Just like Prof. Farai said, mixing up non-ionizing radiation source to be Radioactive is a simple QED ignoramus!!


*Prof Farai*
I hope we will all understand the nonsense in this video from this simple explanation. Communication networks of whatever G, for now and in the near future, are generally in frequencies of the order of Giga Hertz (GHz or 10⁹ Hz). Thank God the video revealed this much. Meanwhile, the bulk of energy from the sun (solar radiation) is in the UV frequency range (i.e.10¹⁵ Hz). Now I ask, how can mankind, who has been bathing under the shower of UV radiation from the sun over the ages, now be under any threat of a radiation of energy over 1 million times less energy than UV radiation? That is one point.
Most importantly for us on this platform, there is no application of a technology that is not under any regulatory control by international bodies made up experts from all parts of globe. Most of us have one thing or the other to do with such bodies as WHO, ICNIRC, UNSCEAR, etc. If they are unaware of the fears expressed in this video or have been compromised, then we are all guilty. We should stop attending their programmes.

Those are my lecturers.. But Dr Popoola is not in radiation physics

like I said earlier, you've made a lot of assumptions which you ought not to including the fact that those sides you labelled K are equal. I could also make some assumptions totally different from yours and get another answer. I still believe there's a piece missing from the question
those are not assumptions but facts.. We have 2 different isosceles triangles in that shape if you observe very well
